This application claims the benefit of the Patent Korean Application No. 10-2008-0009145, filed on Jan. 29, 2008, and Korean Application No. 10-2008-0009146, filed on Jan. 29, 2008, each of which are hereby incorporated by reference as if fully set forth herein.
1. Field of the Disclosure
The present invention relates to motors, and more particularly, to a motor which can save a production cost and can improve production and reliability; and a method for fabricating the same and a home appliance with the same.
2. Discussion of the Related Art
Though the motor of the present invention may be a motor applicable to a home appliance which is comparatively bulky, such as a washing machine, a dryer, or a dish washer, and has an environment of use which is humid and has a temperature higher than a room temperature; a method for fabricating the same, and a home appliance with the same, the application of the motor is not limited to above.
In general, the motor transmits rotating force of a rotor to a rotation shaft, and the rotation shaft drives a load. For an example, the rotation shaft may be connected to a drum of the washing machine for driving the drum, or connected to a fan of a refrigerator to drive the fan for supplying cold air to a required space.
In the meantime, in such a motor, the rotor rotates owing to electromagnetic interaction with a stator. For this, the stator has a coil wound thereon, and as a current is applied to the coil, the rotor is rotated by the stator.
In general, the coil is formed of copper, because the copper has a good electric conductivity and ductility good to have less damage at the time of winding.
However, the copper is expensive to increase the production cost of the motor. Moreover, there have been frequent cases when copper price rises sharply in international market to fail to have a stable supply of the copper.
According to this, it is necessary to use the coil of a material, other than the copper, for saving the production cost of the motor, and have stable supply of the copper. However, even if the coil of a material other than the copper used, it is required to fabricate the motor having a quality at least the same with a case the copper coil is used.
In the meantime, it is preferable that a related art configuration is not changed even if the copper coil is replaced with a coil of other material, because, if it is required to re-design and re-fabricate other essential configuration even if a cost of the coil is saved, an initial investment is liable to increase, excessively.
